Electropollution • What is it? • Where is it? • How is it created? • Solutions
Electromagnetic Fields • Electromagnetic fields have always existed in nature. They are a direct current (DC) frequency between 0 and 100 Hz or cycles per second. The human body has adapted to this band of frequencies. • brain wave activity (4 – 30 Hz) • heart rate (1 – 2 Hz) • pineal gland – melatonin (10 Hz)
Man-made EMF • “EMF” (electro-magnetic fields) are low frequency (5Hz – 400,000 Hz) • alternating current (AC) made up of both electrical fields and magnetic fields • generated by ‘live’ electrical wires • determined by voltage (higher the voltage, the stronger the field) • travels a distance of 6 – 8 ft and further • exists even when device is not in use
Sources of Electrical Fields • house wiring in ceilings, walls, floors • power and extension cords, power bars • electric blankets, waterbeds, TV’s, computers, electronic devices • high voltage power lines
AC Magnetic Fields • produced by flow of electrical current • travel through equipment and wiring • the more powerful the device, the higher the field • field remains close to source – (2-3 ft) • can travel several hundred feet (high voltage power lines)

‘Dirty’ Electricity • harmonic ‘noise’ imposed on a 60 Hz line • measured at the wall plug with a meter • influenced by appliances and lights • can travel a distance of from 2 to 3 homes away
